In today's world, we are witnessing simultaneous breakthroughs in reproductive technologies, genomics, and molecular biology. Advances in molecular genetic technology and understanding of the bovine genome have led to the development of tools that can be used to enhance profitability on cow-calf enterprises. Factors Affecting Calf Crop: Biotechnology of Reproduction provides a detailed compilation of current and forthcoming technology for managing reproduction in cattle.

The book discusses topics such as: approved techniques for controlling the estrous cycle in cattle; managing follicular growth with progesterone, estrogens, and prostaglandins; freezing, thawing, and transfer of cattle embryos; application of embryo transfer to the beef cattle industry; embryo transfer in topically adapted cattle; new factors affecting bull fertility; embryo collection and utilization technology, in vitro fertilization, somatic cell cloning, and genetic technologies; uses of real-time ultrasound; and sexed semen.

Over 25 leading animal scientists have combined their expertise to produce the first single-source reference that covers successful reproductive techniques that will, most likely, be the wave of the future. Expansive in scope, the book addresses current biotechnologies as they impact the production of beef cattle. Written at a level to appeal to the researcher, commercial producer, or student, Factors Affecting Calf Crop: Biotechnology of Reproduction presents you with a wealth of technologies applicable to animal agriculture.

This book provides an environmental 'way in' to the science every primary science teacher needs to know under the ITT National Curriculum issued by the Teacher Training Agency. It builds constructively on the knowledge of and involvement in environmental issues possessed by practicing and student teachers, whether specialist or non-specialist scientists. Especially for the latter, science can be a daunting and difficult area of their teaching. The authors believe that, by way of an environmental emphasis, the science underpinning such practice can be acquired by most students, enabling them to build their confidence as effective science teachers, while developing environmental awareness and understanding in primary children.

An amazing insight into the lives of these intelligent and mysterious creatures, this title helps you learn how elephant bodies work, from the many uses of their versatile trunks and big flapping ears, to their 'conveyor-belt' teeth and mighty tusks. It comes with stunning images by top wildlife photographers, as well as superb illustrations and detailed cross-sections. Special picture sequences zoom in closer, to focus on topics such as the dominance of the bull elephant, and trained elephants that work with human beings. It is perfect for home and classroom use by 8- to 12-year-olds, supplementing school studies on life processes in the natural world. Elephants are the largest and heaviest creatures on land. You can discover the complex way in which these remarkable mammals communicate with each other, and examine the differences between the African and Asian species. There are sections on elephant senses, temperature control, migration, feeding, courtship, growing up, prehistoric ancestors, interaction with humans, conservation and much more. Five special focus spreads allow you to observe particular aspects of these animals' lives, such as the birth of a calf and their love of water.

For one-semester, non-majors introductory biology laboratory courses Thinking About Biology: An Introductory Lab Manual offers an extensively class-tested approach to the introductory biology laboratory course. The manual enables students to see how scientists work to solve problems through scientific investigation by asking questions and answering them through observations and conducting experiments. This lab manual helps students gain practical experience to better understand lecture concepts, acquire the basic knowledge needed to make informed decisions about biological questions in everyday life, develop the problem-solving skills that will lead to success in school and a competitive job market, and learn to work effectively and productively as a member of a team. The 6th Edition features new and revised activities based on feedback from students and faculty.

The Effective Teaching of Biology aims to identify the special dimensions of the subject, how it contributes to the curriculum as a whole and why the teaching of biology differs from the teaching of other subjects. Current legal and safety requirements are provided together with practical teaching ideas and sources of information. The book also covers contemporary issues which are the subject of extensive debate, such as the changing patterns of assessment of pupils, the use of living organisms in school and the nature of learning difficulties which pupils experience.

This title is intended for ages 6-12. Few books explain the scientific classification of animals as well as this one. All creatures, including insects, mammals, and fish, are classified and described from simple animals like sponges to the larger brained mammals such as humans. Young readers will learn: all the basics of kingdoms and species that form an important foundation for the study of biology; the threat to habitats by illegal hunting, human development, and pollution; how readers can help prevent their destruction.

For high school biology students and college zoology students, as well as for all students of nature, this coloring book teaches the structure and function of the major animal groups, from simple to complex. Brief, informative texts accompany each drawing.
